| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-05-30 | CVE-2024-36023 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Julia Lawall reported this null pointer dereference, this should fix it. | 5.5 |
| 2024-05-24 | CVE-2021-47516 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: nfp: Fix memory leak in nfp_cpp_area_cache_add() In line 800 (#1), nfp_cpp_area_alloc() allocates and initializes a CPP area structure. | 5.5 |
| 2024-05-24 | CVE-2021-47518 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: nfc: fix potential NULL pointer deref in nfc_genl_dump_ses_done The done() netlink callback nfc_genl_dump_ses_done() should check if received argument is non-NULL, because its allocation could fail earlier in dumpit() (nfc_genl_dump_ses()). | 5.5 |
| 2024-05-24 | CVE-2021-47520 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: can: pch_can: pch_can_rx_normal: fix use after free After calling netif_receive_skb(skb), dereferencing skb is unsafe. Especially, the can_frame cf which aliases skb memory is dereferenced just after the call netif_receive_skb(skb). Reordering the lines solves the issue. | 7.8 |
| 2024-05-24 | CVE-2021-47521 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: can: sja1000: fix use after free in ems_pcmcia_add_card() If the last channel is not available then "dev" is freed. | 7.8 |
| 2024-05-24 | CVE-2021-47522 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: HID: bigbenff: prevent null pointer dereference When emulating the device through uhid, there is a chance we don't have output reports and so report_field is null. | 5.5 |
| 2024-05-24 | CVE-2021-47541 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net/mlx4_en: Fix an use-after-free bug in mlx4_en_try_alloc_resources() In mlx4_en_try_alloc_resources(), mlx4_en_copy_priv() is called and tmp->tx_cq will be freed on the error path of mlx4_en_copy_priv(). After that mlx4_en_alloc_resources() is called and there is a dereference of &tmp->tx_cq[t][i] in mlx4_en_alloc_resources(), which could lead to a use after free problem on failure of mlx4_en_copy_priv(). Fix this bug by adding a check of mlx4_en_copy_priv() This bug was found by a static analyzer. | 7.8 |
| 2024-05-24 | CVE-2021-47542 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: qlogic: qlcnic: Fix a NULL pointer dereference in qlcnic_83xx_add_rings() In qlcnic_83xx_add_rings(), the indirect function of ahw->hw_ops->alloc_mbx_args will be called to allocate memory for cmd.req.arg, and there is a dereference of it in qlcnic_83xx_add_rings(), which could lead to a NULL pointer dereference on failure of the indirect function like qlcnic_83xx_alloc_mbx_args(). Fix this bug by adding a check of alloc_mbx_args(), this patch imitates the logic of mbx_cmd()'s failure handling. This bug was found by a static analyzer. | 5.5 |
| 2024-05-24 | CVE-2021-47550 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/amdgpu: fix potential memleak In function amdgpu_get_xgmi_hive, when kobject_init_and_add failed There is a potential memleak if not call kobject_put. | 5.5 |
| 2024-05-24 | CVE-2021-47571 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: staging: rtl8192e: Fix use after free in _rtl92e_pci_disconnect() The free_rtllib() function frees the "dev" pointer so there is use after free on the next line. | 7.8 |
